About the OCS

WHO IS THE OCS

THE ONTARIO CONSTRUCTION SECRETARIAT HAS HOSTED FUTURE BUILDING FOR OVER13 YEARS SINCE 2001

The Ontario Construction Secretariat (OCS) was formed in 1993 to represent the collective interests of the unionized construction industry in Ontario’s industrial, commercial and institutional (ICI) construction sector.

Research is the foundation of the OCS that underpins each of the OCS strategic objectives: Improved Labour Relations; Positive Perceptions of Unionized Construction; and Supportive Public Policy.

Our stakeholders include the twenty-five unionized construction trades and their contractor partners. Representing over 100,000 union members and 5,000 union contractors, the OCS is a trusted leader in delivering non-partisan and impartial research and advice to our industry and government stakeholders.
